Welcome to Caddy

Caddy is a powerful, extensible platform to serve your sites, services, and apps, written in Go. If you're new to Caddy, the way you serve the Web is about to change.


Most people use Caddy as a web server or proxy, but at its core, Caddy is a server of servers. With the requisite modules, it can take on the role of any long-running process!

Configuration is both dynamic and exportable with Caddy's API. Although no config files required, you can still use them; most people's favorite way of configuring Caddy is using the Caddyfile. The format of the config document takes many forms with config adapters, but Caddy's native config language is JSON.

Caddy compiles for all major platforms and has no runtime dependencies.

First time?

No problem! We suggest that everyone regardless of experience go through our Getting Started guide. It will give you a well-rounded perspective on your new web server that will be invaluable as you continue learning.

If you only have a few minutes and need to hit the ground running, try one of our quick starts.

For expanded content like specific examples, check out our community wiki - then contribute to it!

We recommend sticking to these official resources to install, configure, and run Caddy, rather than running commands or copying config snippets from random blogs and Q&A boards. You will find that our material is generally more accurate and up-to-date. We also encourage you to craft your own configurations to ensure that you understand how your server works so you'll be more able to fix problems if they arise later on.

But whatever you do, enjoy using your new web server. Caddy is an experience unlike any other server software you've used!
